example 1

[0045] Bioassay example 1: The virulence determination of spirofen-ethyl and indoxacarb on beet armyworm and red spider

[0046] Test subjects: resistant beet armyworm and red spider

[0047] Test method: Refer to the guidelines for the indoor bioassay of insecticides and pesticides "The People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and the creation of the pesticide biological activity evaluation SOP (Insecticide Roll), using the spray method. Select third-instar larvae that grow uniformly and connect them to a 9 cm diameter petri dish containing 10 grams of fresh artificial feed, 10 larvae per dish, 5 dishes per treatment, and spray with a Potter spray tower at 50 PSI. Spray one dish at a time, spray 1 ml of liquid medicine per dish, and spray the same amount of water for the blank control. Generally, 6 concentration gradients are set for each treatment. Put the treated petri dish into a 25°C, 12H / 12H light incubator for culture, check the number of ...

Embodiment 1

[0060] Example 1: 41% spirodiclofen·indoxacarb wettable powder

[0061]

[0062] The active ingredients and various auxiliary agents are fully mixed according to the proportion of the formula, and after being pulverized by an ultrafine grinder, 41% spirodiclofen·indoxacarb wettable powder is obtained.

[0063] The indoxacarb in this embodiment can be replaced with chlorantraniliprole, tolfenpyrad, chlorfenapyr, fenflurane, flubendiamide, or halfenuron, and the new formula is formed according to the same method and formula ratio. 的实施例。 Example.

[0064] The 41% spirodiclofen·indoxacarb wettable powder prepared in Example 1 is used to control cotton bollworm and red spider. The 41% spirodiclofen·indoxacarb wettable powder was diluted and sprayed with water by 4000 times, and the control effects on cotton bollworm and red spider were 83.5%, 93.2%, 90.2% and 87.2, respectively, 1 day, 7 days and 15 days after application. %, 97.1%, 93.5%. 240g / L spirodiclofen suspending agent is 3000 t...

Embodiment 2

[0065] Example 2: 21% spirodiclofen· Chromafenozide suspension

[0066]

[0067]

[0068] The active ingredients, dispersant, wetting agent, antifreeze, thickener, defoamer and water are mixed uniformly according to the proportion of the formula, and 21% spirodiclofen·cyclofenonil is obtained by grinding with a sand mill Hydrazine suspension agent.

[0069] The Chromafenozide in this embodiment can be replaced with indoxacarb, chlorantraniliprole, tolfenpyrad, fenflurane, flubendiamide, or halfenuron, and a new product can be formed under the same conditions and formula ratio. 的实施例。 Example.

[0070] The 21% spirodiclofen·Chromafenozide suspension prepared in Example 2 is used to control wheat armyworm and red spider. The 21% spirodiclofen· Chromafenozide suspension was diluted and sprayed with water by 2500 times, and the control effects on armyworm and red spider were 94.7%, 96.2% and 94.5%, 91.6% 7 days and 15 days after application. The 240g / L spirodiclofen suspension is 3000 t...

Abstract

The invention discloses a compounded pesticide composition containing spirodiclofen. Effective ingredients of the compounded pesticide composition comprise a component I and a component II, wherein the component I is spirodiclofen, the component II is one of indoxacarb, chlorantraniliprole, tolfenpyrad, chromafenozide, pyridalyl, flubendiamide and chlorfluazuron, and the mass ratio of the component I to the component II is (40: 1) to (1: 40). Meanwhile, the invention further discloses preparation dosage forms which are prepared from the composition and are applicable to agricultural use, and application of the composition in crop pest control. The compounded pesticide composition containing spirodiclofen, disclosed by the invention, has obvious synergism, is applied to the pest control of crops, such as fruit trees, cotton, wheat, vegetables, flowers and plants, paddies and the like, and particularly has remarkable preventing and treating effects on lepidopteran pests and acarid pests.

Description

[0001] This application is a divisional application for "a compound pesticide composition containing spirodiclofen and its preparation". The original application date was June 12, 2012, and the original application number was 201210192832.9. Technical field [0002] The invention relates to an insecticidal pesticide composition, in particular to a compound pesticide composition containing spirodiclofen and a preparation thereof. Background technique [0003] In recent years, due to single use of drugs and unscientific use of drugs, many pests have become resistant to the pesticides currently used, especially the cabbage caterpillar, plutella xylostella, armyworm, lamp moth, Chinese cabbage borer, armyworm, Chilo suppressalis, and rice worm. Lepidopteran pests such as leaf rollers and cotton bollworms and mites such as red spiders and spider mites have become a major problem in the chemical control of pests. [0004] Spirodiclofen is a new type of quaternary keto acid acaricide. The...
